Rob Gronkowski, the tight end for the New England Patriots, was apparently injured against the Cleveland Browns on Sunday afternoon.

Gronkowski appeared to suffer a leg injury.

He went down in the third quarter, and he was shown getting carted off the field.

The nature of the injury was not immediately.

When Gronkowski is in, the Patriots average more than 10 points more per game.
